Perrin [15-21 WRX/STI] Gurney Flap for Premium Wing

The PERRIN Gurney Flap adds aggressive styling to your low-profile trunk spoiler. Without looking too intrusive, the Gurney flap modification adds a small amount of height to your existing spoiler for a clean, clearly modified look. Professional flow analysis showed it decreases overall lift while only slightly increasing drag - increasing downforce by 35 lbs. at 75 mph, 62 lbs. at 100 mph, and nearly 100 lbs. at 125 mph.
